WILHELM HOBERG, OF SCHALKSMITHLE, GERMANY.

SCYTHE.

To all whom it may concern:

Be it known that I, WILHELM Honnno, a subject of the Emperor of Germany, residing at Schalksmiihle, WVestphalia, Germany, have invented certain Improvements in Scythes, of which the following is a specification.

This invention relates to a scythe of the kind provided at one edge with lips between which to receive and clamp a detachable edge-blade, and consists in the provision on the edge-blade of a bead carried along its rear edge and adapted to be slid longitudinally into position between the lips. A tapering socket is moreover provided just behind the point of the edgeblade to receive and clamp the pointed end of the scythe-blade and so to hold the elements in position while the tool is being used.

In the accompanying drawings the invention is illustrated, Figure 1 representing a plan view of the complete scythe blade, Fig. 2, a plan view of the detachable edge-blade alone, Fig. 3, a cross-sectional View of the connected blades, and Fig. 4, a view on an enlarged scale of the points of the blades.

The cutting edge of the scythe-blade a is formed of a separate, thin blade (I provided all along its rear-edge with a head 0. To receive and hold. said edge-blade, the blade a is provided on its edge with a groove formed by two lips which are adapted to take around the bead o and to grip the blade resiliently with their outer edges. In the present instance one of the lips is formed by the outer margin of the blade (1 itself, and the other by a separate strip .7) which is riveted there- Specification of Letters Patent.

to. Any other arrangement may, however, be resorted to. The blade (Z is slid longitudinally into the groove in the blade (4. To secure the edge-blade in position and to strengthen its point, said blade is fitted, in any suitable manner, just behind said point with a tapering socket f adapted to receive and grip the point of the blade (I, as shown clearly in Fig. 4.

A scythe-blade made in this manner has the advantage that, while the large blade a may be made of inferior material the small blade (Z can, without much expense, be made of the very best. B y thus employing the best material. for the blade (Z the cutting-effect. ot' the scythe is considerably enhanced, particularly since the thin blade allows a very fine and yet strong edge to be made.

If the blade (Z is snugly fitted in the groove no entrance of moisture into the latter need take place.

In a scythe, of the character described, the combination with a scythe-blade having lips formed along its front edge, of an edgeblade having a bead on its rear-edge to be clamped between said lips, the latter allowing the blade to he slid longitudinally between them, and a tapering socket formed just behind the point of the edge-blade to receive and clamp the point of the other blade, substantially as and for the purpose set forth.
